It's perfectly possible in theory, but highly improbably in practice.

If Einstein was correct, then time is dependent on the speed you travel with. So if you'd be traveling faster then light, you could travel back in time.

If on the other hand you'd be slower then not moving you'd travel forward in time.

There's only slight catch to both...

Things with have any mass at all (and all existing things in our universe have mass) can not reach the speed of light (let alone go faster). While on the other hand to be slower then standing still would require to be all mass and no energy at all, but guess what, if an object wouldn't have any energy, there's be nothing to hold the atoms together and that object would in fact de-materialise.

So it's possible in theory, but doubt it can ever be done in practice.

so maybe if now somebody build something like chamber which "materialises" ..shattered attoms in the chamber, people in future could maybe travel from future, when they step in to the chamber, being able to travel in timeline: <chamber built, future) and if they travel too much in to the past, they stay dematerialised among dinosaurs o_O ..or near hitler=)

btw

In that way it would be probably that you'd do more damage by not going into the past.[/b]

it Would do more harm if you didnt travel back, but you are just not able not to do so (cause its constant). so if its constant, we can do whatever we want, everything is already "written"

That's the big question. Is everything already writen or is the future an open book?

Come to think of it...

If the future is already written then you can't change anything. But if it's not, can you then even travel into the future? I mean, is it already there?
